Abstract
The invention discloses an insecticidal composition comprising pyriproxyfen, the insecticidal composition comprises an active component A and an active component B, the active component A is selected from the pyriproxyfen, the active component B is selected from any one of the following compounds: methoxyfenozide, furan tebufenozide, tebufenozide and chlorine tebufenozide, and the weight ratio of the active components A to the active component B is 1: 80-60:1. The insecticidal composition has a synergistic effect on a plurality of insect pests damaging agricultural production, can reduce the pesticide dosage, reduce pesticide residues in crops, and reduce environmental pollution, is safe to human and livestock, and has good environment compatibility, and the insect pests have low tendency to produce resistance to the insecticidal composition.
Description
Technical field
The invention belongs to technical field of pesticide, relate to a kind of application of Pesticidal combination on crop pests of pyriproxyfen-containing.
Background technology
Nylar (pyriproxyfen) chemical name: 4-Phenoxyphenyl (RS)-2-(2-pyridine radicals oxygen) propyl ether.Nylar is a kind of chitin synthesis inhibitor of juvenile hormone type, has strong ovicidal action.Nylar also has interior absorption transfer activity, can affect the larva be hidden in after blade back.Inhibitory action on insect shows that affecting insect changes in quality and breed.To the toxicological test performance of prodenia litura, Nylar retains the hemolymph middle and high concentration, accelerates the secretion of insect prothoracotropic hormone; On the other hand, because Nylar can make insect, lack the required stimulus of laying eggs, suppress the hatching of embryonic development and ovum, or generate and there is no the ovum of viability, thereby effectively control and reach the purpose of control of insect.
Oxygen worm hydrazides, furan tebufenozide, worm hydrazides, chlorine worm hydrazides belong to the bishydrazide insect growth regulator, IGR.The bishydrazide insect growth regulator, IGR is that a class of developing successively in recent years is efficient, selectivity is strong, environment amenable insect growth regulator, IGR, its action target is the same with insect moulting hormones (20E), be incorporated into the heterodimer of ecdysone receptor (EcR)-superfluous valve albumen (USP), induce transcribing of insect early gene, but the sustainable existence due to bishydrazide compounds in insect bodies, make 20E not exist event in situation not carry out, as DOP Adecarboxylase (DDC), isogenic expression is obstructed, not synthetic chitin, eclosion hormo can not discharge, finally make the precocious decortication of larva and death.
Yet, in the real process of agricultural production, the problem that pest control the most easily produces is the generation of pest resistance to insecticide.The different cultivars composition carries out composite, is the very common method of control resistant insect.Heterogeneity is carried out composite, according to practical application effect, judge certain composite be synergy, add and or antagonism.In most cases, the composite effect of agricultural chemicals is all additive effect, and the seldom composite of synergistic effect really arranged, especially synergistic effect very obviously, co-toxicity coefficient very high composite just still less.Through inventor's research, can produce good synergistic effect after discovery is composite by Nylar and methoxyfenozide, furan tebufenozide, worm hydrazides, chlorine worm hydrazides, and composite relevant report is not yet open about Nylar and methoxyfenozide, furan tebufenozide, worm hydrazides, chlorine worm hydrazides.
Summary of the invention
The Pesticidal combination of a kind of pyriproxyfen-containing that the objective of the invention is to propose to there is synergistic function, use cost is low, preventive effect is good.The Pesticidal combination that the present invention proposes contains active components A and active component B.
A kind of Pesticidal combination of pyriproxyfen-containing, contain active components A and active component B, it is characterized in that: the weight ratio of active components A and active component B is 1 ︰ 80 ~ 60 ︰ 1, described active components A is selected from Nylar, active component B is selected from a kind of in methoxyfenozide, furan tebufenozide, worm hydrazides, chlorine worm hydrazides, and active components A and the preferred weight ratio of active component B are 1 ︰ 60 ~ 30 ︰ 1; More preferably the weight ratio of Nylar and methoxyfenozide is 1 ︰ 20 ~ 20 ︰ 1, the weight ratio of Nylar and furan tebufenozide is 1 ︰ 30 ~ 15 ︰ 1, the weight ratio of Nylar and worm hydrazides is 1 ︰ 40 ~ 10 ︰ 1, and the weight ratio of Nylar and chlorine worm hydrazides is 1 ︰ 30 ~ 15 ︰ 1.
The purposes of the Pesticidal combination of described pyriproxyfen-containing for preventing and treating insect on fruit tree, vegetables, cereal crops, fiber crop, legume crop, forest.
Described insect comprises: trialeurodes vaporariorum, Bemisia tabaci, pear sucker, heart-eating worm, scale insect, caterpillar, cabbage caterpillar, thrips, beet armyworm, prodenia litura, golden Autographa spp, leaf roller, slug moth, cotton bollworm, rice leaf roller, striped rice borer, paddy stem borer, tea geometrid, aphid, rice fulgorid, flea beetle.
The weight ratio of active components A, active component B is 1 ︰ 80 ~ 60 ︰ 1.Usually in composition, the weight percentage of active component is gross weight 0.5%～90%, is preferably 5%～80%.According to different preparation types, the active component content scope is different.Usually, liquid preparation contains 1%～70% active substance by weight, is preferably 5%～50%; Solid pharmaceutical preparation contains 5%～80% active substance by weight, is preferably 10%～80%.
At least contain a kind of surfactant in Pesticidal combination of the present invention, the dispersion of active component in water while being beneficial to use.Surface-active contents is 5%～30% of total formulation weight amount, and surplus is solid or liquid diluent.
The selected surfactant of Pesticidal combination of the present invention is known in those skilled in the art: can be selected from one or more in dispersant, wetting agent, binding agent or defoamer.According to different dosage form, in preparation, can also contain disintegrant known in those skilled in the art, antifreeze etc.
Pesticidal combination of the present invention can be by the user before use through dilution or directly use.Its preparation can be by common processing method preparation known in those skilled in the art, be about to active substance and after liquid flux or solid carrier mix, then add surfactant as one or more in dispersant, stabilizing agent, wetting agent, binding agent, defoamer etc.
